(CNN) - Former Utah Gov. Jon Huntsman piled on criticism of Texas Rep. Ron Paul's past Thursday as he continued to hone his focus on New Hampshire with a new web ad.
In the one minute web video, Huntsman questioned Paul's integrity.
As the rest of the 2012 field flocks to Iowa ahead of the Hawkeye State's Jan. 3 caucus, Huntsman remained solely trained on the Granite State's primary held seven days later, where he's been banking on a top finish.
Huntsman's ad targeted Paul, currently ranked second in a new CNN/Time/ORC International poll released Wednesday with 16% support among likely New Hampshire primary voters. Nine percent of likely New Hampshire voters backed Huntsman in the poll, placing him fourth, behind Romney in first and Gingrich in third.
The ad begins with two spliced archival videos of the Texas congressman stating, "I deliver babies for a living but I also do an investment letter…it's called the 'Ron Paul Survival Report' and it covered a lot of what was going on in Washington." The footage of Paul is followed by news coverage of racist and anti-gay statements written in several newsletters also bearing Paul's name.
When controversy over the contents of 1980s and 1990s newsletters written with his moniker reemerged recently, Paul dismissed criticism by asserting that he'd long since disavowed the questionable content and insisting the story was old.
But it wasn't too old for Huntsman, who asked voters at the end of the spot, "Can New Hampshire voters really trust Ron Paul?"
